Interactive training versus self-driven training in the prediction of colorectal polyp histology by trainees using the NICE classification.

Overall, self-driven training showed comparable accuracy of NICE classification, vessel pattern, and surface pattern to interactive training, but lower accuracy of color analysis. This method showed comparable effectiveness and is more applicable than interactive training. It is worth spreading during the COVID-19 pandemic.
